Setup Average Equation:
| Average = | Sum of our 3 numbers + unknown score of x |
| Total Numbers |
| 80 = | 73 + 75 + 79 + x |
| 4 |
Cross Multiply
73 + 75 + 79 + x = 80 x 4x + 227 = 320
Subtract 227 from both sides of the equation to isolate x:
x + 227 - 227 = 320 - 227x = 93
What is the Answer?
x = 93
